Definitions

  • the invention relates to electro-optical devices whose electromagnetic radiation absorption characteristics can be selectively altered by the influence of a suitably controlled electric field. More particularly, the invention relates to variable light transmission devices which contain a layer of persistent electrochromic material as a light modulating material, and a counter-electrode separated by an ion conducting material. In specific, the invention is directed to a simplified, effective counter-electrode for eletrochromic devices and a method for forming such counter-electrodes.
  • FIG. 1 is an exploded perspective view of an electrochromic device including the paper counter-electrode of the present invention.
  • a paper electrode 6 is utilized as the counter-electrode.
  • Substrate 7 may be glass, metal or plastic, and the like and need not be transparent, depending on the desired product application.
  • the paper electrode may be bonded to the substrate by means of an adhesive. If the adhesive is electrically conductive and the substrate also is electrically conductive, electrical connection may be more conveniently made to the substrate rather than to the paper electrode directly.
  • the paper counter-electrode basically is a carbon-filled fibrous sheet.
  • a preferred fiber used is an acrylic fiber and a fluorocarbon resin such as a Teflon (polytetrafluoroethylene) binder may be incorporated to provide a more cohesive sheet.
  • An electrochromic material may also be incorporated on the sheet.
  • a preferable material is WO 3 .
  • a sheet of carbon impregnated fibrous acrylic material was then formed by standard papermaking procedure and then dried under pressure at 70° C. to 120° C.
  • the dried sheet next was soaked for 2 hours in 10% H 2 SO 4 in isopropanol in order to remove impurities introduced in processing. Following this soaking, the sheet further was rinsed in isopropanol for 1 hour and vacuum dried for 1/2 hour at 80° C.
  • the sheet was pressed at 1.2 kg/cm 2 to produce a 0.012 inch thick sheet which can be cut to desired size.
